Dan

In with the twins too. Dan's car is so good with the 99's it is hard to imagine that the power band could be better, but we have discussed the idea of a BNR hybrid setup if it could be made.

I disagree. While most FDs I have driven have this characteristic, it can be tuned out. Dan's car has a very smooth power curve and the only real way you know that you are in the 2nd turbo is by the change in the pitch of the engine and the fact that everything looks like it is in fast forward . I was able to hop in his car and be very fast out of the box despite the fact that I have driven a low horsepower (114 to the wheels) E Stock Miata for the past 6 years.
